Question

when determining soil texture, the percentages of the three soil particle types add up to 100%. if a soil had 10% clay and 10% silt, what would be the percentage of sand?

Explanation:

Step1: Set up the equation

Let the percentage of sand be \(x\). We know that the sum of the percentages of clay, silt, and sand is \(100\%\). So, \(10\%+ 10\%+x = 100\%\)

Step2: Solve for \(x\)

Simplify the left - hand side of the equation: \(20\%+x=100\%\). Then, subtract \(20\%\) from both sides: \(x = 100\% - 20\%=80\%\)

Answer:

\(80\%\)
